Dome rooflights in Redruth: what is involved?
We handle dome rooflights across Cornwall, including Redruth. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. In Redruth, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
We work across Cornwall, including Redruth, and in neighbouring towns such as Camborne and Truro. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Redruth project
- Insulated PVC or GRP upstands
- Polycarbonate or acrylic
- Fall-through protection mesh
- Twin, triple or quad skin
- Fixed or hinged with vent
- Quick replacement on existing upstands
- Fixed, hinged or vented options
Things we check at survey
- Fire classification matters on some roofs
- Upstand condition decides whether you replace dome only or the whole unit
Building control and safety duties in Redruth
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. We confirm the route for your building before ordering.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.
Our planning guide covers each nation in more detail.

Dome rooflights in Redruth: questions
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Do you fit dome rooflights in Redruth?
Yes. We survey and fit dome rooflights in Redruth and across Cornwall. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Redruth?
